Abstract: A system for treating a wound, having a wound treatment device, a fluid input upstream side of the device, a fluid output downstream of the device; an air inlet valve upstream of the fluid output; an actuator to drive the air inlet valve between open and closed positions; a pump downstream of the fluid input; a motor to drive the pump to provide a negative pressure to the device; and a controller in configured to operate the air inlet valve and the pump. The controller is configured to (i) open the air inlet valve and operate the pump to maintain a first vacuum pressure at the wound treatment device and introduce air into the device, and (ii) close the air inlet valve and operate the pump to maintain a second vacuum pressure at the wound treatment device and remove air and fluid from the device.
